Water in pump cone?

A little advice please if anybody can help. Had first service done on my spark by a independent mech.
although its not in the service schedule to remove the pump, he did so to check over properly.when removing the plastic pump cone there was about an egg cup full of water.on closer inspection the pump shaft has a Teflon coating on one end which was pimpling up a bit, so thought that may be the problem?
i got him to put it back together as I wanted to ski over the Christmas holiday, as its nice and warm in the UK,not lol but the best time of year to ski
so I'm thinking,
1-how long would it be ok for? Not long before bearings are shot I guess.
2-this wouldn't have been picked up by a dealer on a first service, so is it something that should checked
3-would this be warranted or is it just a wearable part?
The ski has done 33hrs.
Cheers in advance

Did he just pull the cone, or did he disassemble the whole pump? Were there signs of rust anywhere?

Hi, BryanP
He disassembled the whole pump, no signs of rust at all and the grease looked fine although not a lot of it!
i was amazed how clean and dry the hull was when the top was removed, I sprayed everything with fluid film while I had the chance. Hope that was a good idea!

Don't tell the dealer that a non authorized BRP worked on it.
In Australia that is enough for them to knock back any claim BS I Know.

Ride it get some water back in it then go back and say the pump is making strange noises fix under warranty please.

I have removed the grease from mine and gone back to gear oil IMO it worked very well back in the old 97 XP and the Honda I changed over from grease as well I think the oil goes every where when it spins all up into the seals but once the grease comes out from the bearing you got nothing this is what be the problem some people are having the grease comes out starts to heat up more then burns the seals in comes water
